Electron is an elementary particle (according to contemporary knowledge, I mean Standard Model), but proton and neutron are not. They both consist of three quarks: neutron - one up, two down quarks, proton - one down, two up ones. But masses of quarks are also not equal to the mass of electron. The reason of that is one of the top question of the nowaday physics.
What else can I help you with?
How are protons different from neutons?
They have little bit simillar mass. But there are no charge on neutrons.
What is the atomic mass of oxygen-15?
The atomic mass of oxygen-15 is 15. The atomic mass consists of protons and neutons, and oxygen-15 has 8 protons and 7 neutrons.
Where is the most of the mass in an atom?
Most of the mass in an atom is in the nucleus. The protons and neutrons are about the same weight, 1 amu. The elecrtons are 1/1840 of the mass of an proton. Neutrons are 2000 times heavier than electrons and protons have an equal mass of neutrons
Sum of protons and neutons?
The sum of protons and neutrons in an atom is referred to as the atomic mass. It is also known as the mass number of an atom and is an important parameter in determining the overall stability and properties of an element. To calculate the atomic mass, you can simply add the number of protons and neutrons present in the nucleus of the atom.
What is property protons and neutons have in common?
Protons and neutrons both have mass and are located in the nucleus of an atom. They are made up of quarks and are essential for the stability and structure of the atom.
Do protons electons and neutrons differ in mass?
As I remember neutrons and protons weight something similar, electrons have a far smaller mass which is negligable in comparison to the weight of protons.
How is atomic number differ from mass number?
atomic mass is the number of protons in an atom mass number is the number of protons plus neutrons in an atom
How does the mass of a nucleus differ from the mass of an electron?
There is no simple answer.The mass of a nucleus depends on the number of neutrons and protons in the nucleus. The number of protons in the nucleus depends on the element. Moreover, the number of neutrons can vary between isotopes of the same element.
How many neutons are in an atome of sulfur with a mass number of 35?
Sulfur is a non metal element. Mass number of it is 32.
What is it called when the atoms only differ in the number of protons?
When atoms only differ in the number of protons, they are considered isotopes of the same element. This difference in the number of protons results in variations in atomic mass but not in chemical properties.
In what way do these atoms corresponds and in what way do they differin terms of their mass numbers?
Atoms correspond in that they are all made up of protons, neutrons, and electrons. However, they differ in their mass numbers, which is the sum of protons and neutrons. Atoms of different elements have different mass numbers due to varying numbers of protons and neutrons.
Do isotopes of the same element differ in mass number?
isotopes just mean they have a different number of neutrons so if the..Mass number = # of protons + # of neutrons -they will have a different (greater) mass
